What we serve Microwave Data Microwave Dataset Holdings at GHRC GHRC and its predecessor • programs have been ingesting, processing, archiving and distributing microwave data for over 35 years o MSU, SSMI, AMSU, AMPR, TMI, AMSR-E This climate sensitive data record extends back to 1978 providing • an unbroken inventory of climate information that continues today GHRC is also recognized as one of the primary data centers for microwave data

DISCOVER MEaSUREs Project a key source for microwave data D istributed I nformation S ervices for C limate and O cean Products and V isualizations for E arth R esearch A NASA MEaSUREs project to create Earth system data records Frank Wentz (RSS), PI, with MSFC and UAH • Science Objective: providing highly accurate, long- • term ocean and climate products, and services Information technologies provided by UAH • Data archived at GHRC – DISCOVER products from satellite microwave sensors going back to 1987 User Working Group Meeting 9/25/14 – 9/26/14 6

REGIONAL AIR-SEA INTERACTIONS (RASI) Interactive Climatology System Ken Keiser, Xiang Li, Shannon Flynn University of Alabama in Huntsville Deborah Smith Remote Sensing Systems Presented at the GHRC User Working Group Meeting September 25-26, 2014

Overview • Project Information • Event Detection and Climatology Generation • Demonstration of Interactive Climatology System CCMP winds showing gap winds at Tehuantepec on 03/11/1998

RASI objectives R egional A ir- S ea I nteractions (a DISCOVER MEaSUREs tool) • Develop automated mining solution to extract gap wind and SST (sea surface temperature) events using microwave products. • Generate gap wind and SST event climatology using the automated algorithms. • Distribute event climatology to users through an interactive web application.
